I'm getting the ALC-WKS-007-043 error when I try to sumit a form with the "Complete" button in the workspace. This error does not happen always, but sometimes occurs and may be sumit to the second, third, or more time I click the button. I have reviewed the stack trace from the application server, but the error does not write anything in this. The forms are .pdf or .xdp sumit as PDF.
